LAMP-BURNER.

Specification of Letters Patent.

Patented Dec. 17, 1907.

I Appli ation fil d February 28.1907. Serial No. 359,844.

To all whom it may concern:

Be it known that I, JUSTIN E. Ross, a citizen of the United States,.and a resident of Springfield, in the county of Greene and State of Missouri, have invented a new and Improved Lamp-Burner, of which the following is a full, clear, and exact description.

The invention relates to lamps using kerosene, alcohol or like fluids as the illuminant.

The object of the invention is to provide a new and improved lamp burner, arranged to prevent back flash and thus guard against ignition and explosion of the gas generated and contained in the font or bowl containing the liquid illuminant.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and-then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.

Figure 1 is an enlarged sectional side elevation of the improvement, and Fig. 2 is an inverted plan view of the same, part being shown in section.

The shell A of a lamp burner of any approved construction is provided with the usual threaded neck B screwing into the font or bowl containing the kerosene or other liquid illuminant. Within the shell A is arranged a wick tube 0 extending from the under side of the neck B into the dome D, and on one side of the said wick tube 0 is located the vent tube E, and on the other side is arranged the wick-raising device F of of any approved construction.

The lamp burner thus far described is one of a well known type, and the improvement consists in providing a chamber G on the under side of the neck B, the said chamber being formed by a portion of the under side or bottom of the neck B, and a cap H connected by a hinge I with the said bottom of the neck B. The cap H is provided at its free end with an indentation H engaging a lug J depending integrally from the bottom of the neck B, the said indentation H and lug J forming a fastening device for holding the cap H in a closed position on the under side of the neck B. Lugs J depend from the under side of the neck B and engage the sides of the cap H, so as to hold the latter in proper alinement when in a closed position.

The free end of the cap H is also provided with a small finger piece H adapted to be taken hold of by the operator, for swinging the cap H into an open or a closed position whenever it is desired to do so. The cap H is provided with perforations in its bottom as well as on its side, and the bottom )f the cap is also provided with an eyelet H for the passage of the wick and in register with the wick tube 0 when the cap is in a cl led position. Now when it is desired to nsert a wick in the lamp burner, the cap H 1s preferably swung into an open position so as to permit the operator to readily pass the wick through the eyelet H and to thus engage the wickwith the wick tube 0 and the wickraising device F, after which the cap H is closed.

From the foregoing it will be seen that the wick tube C as well as the vent tube E open into the chamber G, so that any gas generated in the font or bowl of the lamp can readily pass through the perforations in the cap H to the inside thereof, that is, into the chamber G, to pass by way of the vent tube E to the outer air, or, in case the wick is lighted to the flame to be consumed.

It will also be noticed that fresh air can enter by way of the vent tube E and the chamber G into the font, so that the accumulation of the explosive gas therein is prevented, as the gas generated can escape and fresh air can enter the font.

Now in case of a back flash, it is evident that a possible explosion can only occur within the small chamber G, as the perforated cap H will not allow ignition of the gas in the font, and consequently the lamp is not liable to explode.

By arranging the chamber G on the under side or bottom of the neck B, it is completely out of the way of the working parts of the burner, and consequently does not interfere in the least with the use of the lamp as heretofore practised.

The perforated cap H is preferably made elliptical, as shown in Fig. 2, to provide sufficient space for the hinge I and the cap clasp and the finger piece, H

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A lamp burner provided at the under side of its neck with a perforated cap hinged to the neck and having a wick passage in register with the lower end of the Wick tube opening into the said cap, and means for locking the said cap in place against the under side of the neck.

2. A lamp burner provided at the under side of its neck With a cap having perforations in its bottom and sides, the cap being hinged at one side to the under side of the said neck, fastening and alining means for holding the cap locked in place on the undre 10 side of the neck, and an eyelet in the cap for name to this specification in the presence of 15 tWo subscribing Witnesses. 4
